FUEL-OIL BURNER.

Specification of Letters Patent.

Patented Jan. 13, 1920.

Application filed. September 7, 1918, Serial No. 253,044. Renewed August18, 1919. Serial No. 318,316.

To all whom it may concern:

Be it known that we, CznsLAw KoRznNmw- SKI and STEPHEN CHoJNAoKI,subjects of Poland, residing at Cleveland, in the county of Cuyahoga andState of Ohio, have invented certain new and useful Improvements inFuel-Oil Burners, of which the following is a specification.

This invention relates to fuel oil burners of that type embodying aretort which overlies the burner and is exposed to the heat of the flamefor the purpose of generating gas from the fuel oil.

The object of the invention is to form a burner improved particularlywith respect to the means for heating the retort tube, whereby a largeand hot flame is produced and a very efficient operation is obtained,adapting the burner especially for use in furnaces'and the like. Anotherobject of the invention is to provide a quick and ready means forremoving the retort tube from the burner for the purpose of cleaning thetube or replacing it with another tube.

The invention is illustrated in the accompanying drawing in which Figure1 is a side elevation of the burner. Fig. 2 is a section on the line 2-2of Fig. 1. Fig. 3 is a section on the line 3-3 of Fig. 2.

The burner cap is indicated at 6, and comprises a slitted inverted cupshaped cap which rests within a flange 7 at the edge of the upper plate8 of the burner body or head. Depending from the plate 8 is an uprightmixing tube 9 into which the vapor or gas is discharged from a jet hole10 near the end of the pipe 11 which receives its supply from an oilfeed pipe 12 and extends over the top of the burner as indicated at 13and bends down beside the burner to position under the same,dischargingthrough the jet hole 10 into the mixing tube 9. The burnerhead or body also has at one side thereof a depending chamber or passage14 which extends beside and below the mixing tube 9 and communicates atits upper end with the space in the burner head under the cap 6. Theouter side wall of this passage has vertical slit 15 directed toward thevertical part of the pipe 11, and some of the vapor escapes from andburns at these slits to assist in heating said pipe and the oil or vaportherein. The oil tube 11 forms a retort in which the oil is changed togas by the heat of the burner at the top and also by the heat from theflame through the vertical slits 15 in the outer side wall of thepassage 14. 16 is'the starting cup supported by a bracket 17 secured tothe extension 14 and located under the feed pipe 11. By placing a smallquantity of alcohol or the like in the cup and lighting the same,generation is started. 18 is a needle valve controlling the flow fromthe supply pipe to the retort. 19 is a nipple which provides a readymeans for connecting or disconnecting the retort tube with the oilsupply pipe.

In operation, oil fed from the pipe 12 to the retort tube is vaporizedin the latter by the heat of the burner both on top and on the side, andthe vapor is discharged through the jet 10 and mixes with air in themixing tube 9.

We claim:

1. The combination of a burner having a. mixing tube leading into theburner head, and a lateral burner passage communicating with said head,and a retort tube overlying the burner and extending down beside thelateral burner passage and provided with a jet orifice directed towardthe mixing tube.

2. The combination of a burner comprising a hollow head having a capthereon with a chamber under the cap, a mixing tube leading to saidchamber, a lateral burner located beside the mixing tube andcommunicating with said chamber, and a retort tube overlying the burnercap and extending downwardly beside the lateral burner and provided withan extension having a jet orifice directed toward said mixing tube.

In testimony whereof we do affix our signatures in presence of twowitnesses.
